Trying to remove a tick label in dimple.js - javascript

I've built a line-graph in dimple.js that can be found here. http://jsfiddle.net/lukehtravis/0twgc2uL/
You'll notice on the y-axis, there is a little "m" that is automatically generated by dimple and placed next to the numbers as a quantity label.
I combed through the documentation, but couldn't find anything about that little m.
Anyone know how to remove it? Here's the code
// Create the canvas to draw on
var svg = d3.select("#charty")
.append("svg")
.attr("width", 800)
.attr("height", 500);
// Create the chart object | contents of data visible in fiddle link above
var chart = new dimple.chart(svg, data);
//Create the x axis
var x = chart.addCategoryAxis("x", "Day");
x.showGridlines = true;
// Create the y axis
var y = chart.addMeasureAxis("y", "Volume");
y.title = "Volume (AF)";
y.overrideMin = 300000;
y.overrideMax = 1450000;
y.showGridlines = true;
// Add location as data series
var series = chart.addSeries("Location", dimple.plot.line);
// Decorate the lines in the graph
series.lineWeight = 2;
series.lineMarkers = true;
// Create the legend
chart.addLegend(100, 50, 200, 200);
// Draw the chart
chart.draw(3100);

Small m is not but conversion of units into million..
0.3million is your value 300000 .. Its pretty normal and not an error ..
If you dont want that then just add this line y.tickFormat = "1f"; after
y.showGridlines = true;

How do I get rid of the excess white space around pie chart? Using amcharts 4 libs

I have been trying to spread the pie chart I have to cover most of the 'card' I on the page, but no matter how much margin I cut, it either start disappearing behind another border within the card. I noticed that amcharts lib creates a bunch of layers that the developer doesn't have much control over. Anyway, this is what I'm talking about:
Here is the generated HTML code snippet:
Here is my javascript:
am4core.ready(function () {
//Themes
var chartType = am4charts.PieChart3D;
var seriesType = new am4charts.PieSeries3D();
//Create Chart and Series
var chart = createChart(thisWidget.id, chartType);
var pieSeries = chart.series.push(seriesType); // 3D Pie Chart
//Set properties
chart.hiddenState.properties.opacity = 0; // 3D Pie Chart: this creates initial fade-in
pieSeries.slices.template.cornerRadius = 6; //Pie Chart with varying Radius + 3D
pieSeries.colors.step = 3; //Pie Chart with varying Radius + 3D
pieSeries.angle = 45;
//color
if (colorTheme) {
pieSeries.colors.list = getAmchartCustomTheme(colorTheme);
}
//data types
pieSeries.dataFields.value = "count";
pieSeries.dataFields.category = "tag";
chart.paddingTop = 0;
chart.marginTop = 0;
// Put a thick white border around each Slice
pieSeries.slices.template.stroke = am4core.color("#fff");
pieSeries.slices.template
// change the cursor on hover to make it apparent the object can be interacted with
.cursorOverStyle = [
{
"property": "cursor",
"value": "pointer"
}
];
//Make the slice move on hover
var slice = pieSeries.slices.template;
slice.states.getKey("active").properties.shiftRadius = 0;
slice.states.getKey("hover").properties.scale = 1;
slice.states.getKey("hover").properties.shiftRadius = 0.2;
//increase size of Chart
chart.svgContainer.htmlElement.style.height = targetHeight;
chart.svgContainer.autoresize = true;
//disable Ticks and labels to save space
pieSeries.labels.template.disabled = true;
//registering events
pieSeries.slices.template.events.on("hit", function (ev) {
var category = ev.target.slice._dataItem.properties.category;
addInput(category);
});
pieSeries.alignLabels = false;
// Create a base filter effect (as if it's not there) for the hover to return to
var shadow = pieSeries.slices.template.filters.push(new am4core.DropShadowFilter);
shadow.opacity = 0;
// Create hover state
var hoverState = pieSeries.slices.template.states.getKey("hover"); // normally we have to create the hover state, in this case it already exists
// Slightly shift the shadow and make it more prominent on hover
var hoverShadow = hoverState.filters.push(new am4core.DropShadowFilter);
hoverShadow.opacity = 0.7;
hoverShadow.blur = 5;
//Add Data
chart.data = displayItems;
})
strokeOpacity = 0 or strokeWidth = 0 should do the trick.

JSBIN Example
Please take a look at the dual y-axis I created with your data.
There is few things your doing wrong.
var x = chart.addMeasureAxis("x", "Date");
// First y axis is the combination axis for revenue and profit
var y1 = chart.addMeasureAxis("y", "Temperature");
// Second is the units only
var y2 = chart.addMeasureAxis("y", "Energy Consumption");
var bars = chart.addSeries("Energy Comsuption", dimple.plot.bar, [x,y2]);
var lines = chart.addSeries("Weather Report", dimple.plot.line, [x,y1]);
Date, Temperature, Energy Consumption, Weather Report. All of this is not valid, because that not how its define on your data. You have to give exact name as appears on your data.
I only create dual axis for you, I think you can add all the other details starting from there. If you have any other question feel free to post

Responsive sizing of my chart in dimple.js is not working

I have an svg component on my page to which I have appended my dimple chart. I want the chart to be sized responsively.
I have referred to this example in the documentation.
But when I use it in a similar fashion in my line chart, it does not seem to work. My code for a line chart is as follows:
var xpoints = chartData["xdata"];//Populated Dynamically
var ypoints = chartData["ydata"];//Populated Dynamically
var dataset = [];
var line1;
for (var i = 0; i < xpoints.length; i++) {
dataset.push({
x : xpoints[i],
y1 : parseFloat(ypoints[i])
});
}
var svg = dimple.newSvg("#" + mychart, "100%", "100%");
var x, y;
var myChart = new dimple.chart(svg, dataset);
myChart.setMargins("60px", "30px", "110px", "70px");
y = myChart.addMeasureAxis("y", "y1");
x = myChart.addCategoryAxis("x", "x");
line1 = myChart.addSeries("First", dimple.plot.line, [ x, y ]);
line1.lineMarkers = true;
var l = myChart.addLegend(65, 10, 510, 20, "right");
myChart.draw(1500);
window.onresize = function () {
myChart.draw(0, true);
};
Is it that I cannot do this in the same window itself and it is absolutely necessary for me to create a new window, as in the example?
The console does not show any errors, the chart is rendered correctly. It's just that the resize function does not work!
Okay, I found my mistake!
Turns out there is no need to create a new window.
It's just that, I had explicitly defined the height and width of the div (#mychart) to which I was appending my svg and these dimensions were in pixels. So the size of the svg remained the same even on window resize - because it was always 100% of a constant pixel value. So the function was actually firing earlier as well, but was ending up with the same dimensions.
I changed the dimensions of my div to percentage values and everything works fine :D

dimple.js scatterplot duplicating axis lables

Using dimple.js, I am rendering a scatter plot with the code below. This works fine, but when i hover the mouse over any point, the x and y values are shown twice, once as decimal and below that as percentage. How can i simply keep the percentage x,y values in the hover-popup? Also, is there a way to display additional items in the hover-popup?
Here is the fiddle demonstarting the issue: http://jsfiddle.net/dizzy0ny/ch2187dd/52/
var svg = dimple.newSvg("#chartContainer", 600,600);
var myChart = new dimple.chart(svg);
myChart.setBounds(90, 35, 480, 400)
xAxis = myChart.addMeasureAxis("x", "x");
yAxis = myChart.addMeasureAxis("y", "y");
xAxis.showGridlines = true;
xAxis.tickFormat = '.1%'
yAxis.tickFormat = '.1%'
s1 = myChart.addSeries(["x","y","group"], dimple.plot.bubble, [xAxis, yAxis]);
s1.data = data_scatter
s2 = myChart.addSeries(["y","group"], dimple.plot.line, [xAxis, yAxis]);
s2.data = data_ser1
myChart.addLegend(90, 480, 330, 20, "left");
myChart.draw();
As per the docs here: http://dimplejs.org/adhoc_viewer.html?id=adhoc_bar_custom_tooltips
You can change the default tooltip like so:
s1.getTooltipText = function (e) {
return [
"This is a custom tooltip!",
"X value: %" + (e.aggField[0]*100).toFixed(2),
"Y value: %" + (e.aggField[1]*100).toFixed(2),
"Group: " + e.aggField[2]
];
};
Check out your updated fiddle here: http://jsfiddle.net/ch2187dd/55/
Also, try not to forget those semi-colons! :)

Error creating axis d3.js

I've been wrestling with this problem for quite a while now. I want to create an x-axis, so I used the following code:
var w = 1024,
h = 1024,
padding = 20,
fill = d3.scale.category20();
var vis = d3.select("#chart")
.append("svg:svg")
.attr("width", w)
.attr("height", h);
d3.json("force.json", function(json) {
//Create array of dates for the x-axis
var dates = json.nodes.map(function(d) {
return Date.parse(d.date);
});
console.log(dates)
// Create scale from the array of dates
var scale = d3.time.scale()
.domain(dates)
.range([padding, w - padding]);
console.log(scale(dates));
var axis = d3.svg.axis();
//more code below, but error gets called at the line above this comment.
}
However, I get the following error returned consistently:
Uncaught TypeError: Object #<Object> has no method 'axis'
This is very perplexing, as I was simply following the d3 API at https://github.com/mbostock/d3/wiki/SVG-Axes.
Would somebody kindly point out where I'm going wrong?
(for reference, force.json is the data I am working with)
