I want to show a column chart that will show empty columns on days without data. I have previously done this in amCharts, but trying to switch everything over to js charting.
Here is an example:

Basically if I could change the color of individual columns that would also work.

You can set the y value to 100, and set a secondary value to the actual value, which you can then grab in the tooltip formatter.
see this example: http://jsfiddle.net/jlbriggs/BLxUL/
Depending on which you have more of, you can either set the bar color in the plotOptions, and call the 'blank' color in the data array when needed, or the other way around (as in the example)
Thanks jlbriggs!

I am working with Dygraph in python. I want to remove a label from the legend. If you look into the example photo attached bellow you can see "A:2.77 B:2.29". Is it possible to remove the B label, but still use its values and to be displayed in the graph?
Currenlty, in my project self.page().runJavaScript(f'g.updateOptions({{file:{file},labels:{labels}}});') is getting the calculated labels and their values and displaying them. However, if I go and remove part of it , it will be removed from the graph as well.
self.exampleCalculated.emit({'Price (Next 2 days)': example_forecast['price1'][0:48], 'SystemPrice': systemPrice[0:48], 'Other': otherPrice[0:48]})

I have a chart on my page and I want to make it respond to user input to show variations on changing the gap between two points on the axis , something like
so far I have tried using valueAxis.x = my desired value
but it does not change the graph.
How to do that?
First you need to set autogridCount to false
valueAxis.autoGridCount=false;
then you need to use
valueAxis.gridCount = no of grid lines;
here is a fiddle
I am trying to render Google Geochart chart on my page and it renders okay. The only problem with the chart is the scale (colorAxis). As far as I know, from the developers guide, user can put values and colors that should be available on the scale.
The problem is, that I can put there only number values and I would like to change the scale, so it contains four text values - "low, medium, hard, extreme".
Is there any way to change the 1-4 scale to text scale, so min and max values on the scale would be strings, not integers.
I've already tried to put strings in colorAxis.minValue and colorAxis.maxValue but then, chart just ignores that.
colorAxis.minValue and colorAxis.maxValue according to Google Charts documentation are used for:
If present, specifies a minimum value for chart color data. Color data
values of this value and lower will be rendered as the first color in
the colorAxis.colors range.
What you want to change is the legend of the chart. I tried some options, but the best thing i could manage is simply add a string before min and max values with the following option.
var options = {
legend: {
numberFormat: "test"
}
};

I'm trying to create a color-coded bar chart using d3. I am SO CLOSE. Here's my bl.ocks chart:
http://bl.ocks.org/sconnors37/b99070b055f125c9dff1/1cb53954be3f20e3c4492066eccd749b5cf04bbe
What I'm trying to do is assign color values based on the "teams" field in my .tsv file. So grey for Mercedes, red for Ferrari, etc. I have the teams in the var color domain and the colors in the var color range, and I'm pulling var color into the bar attrib.
For some reason though, the entire chart is just taking on the first item in the range - I changed it from grey to red just to see if that was what was going on, and it is.
So! How do I get the rest of my colors to pull through onto the bar chart? Help me, stackoverflow, you're my only hope.
In your .tsv file the last column team is not separated from the previous column by a tab, but rather through two spaces. If you look at the data passed to the d3.tsv callback I think you will find that you have one date team column instead of a date and team column.
This means that the field d.team is undefined and ordinal(undefined) will just return the first value from the range.
I have a Google line chart that contains a few years of data. Each year is a separate series. The chart legends displaying each year/series are clickable and clicking on any given 2 or more of these legends/series, displays them and their corresponding Datapoints and their annotations. In the hAxis, these Datapoints are integers ranging from 1 to aprox. 6,000,000. I also have their values displayed under annotations for each Datapoint.
Notice that when you click on a datapoint, it increases in size and gains a white border. If you unclick it, it returns to it's original form.
My question is:
Is it possible to change my code to look for the top 10 closest-to-each-other integers between 2 series based on a predefined threshhold? I know styling may not be an option but perhaps there may be a way to force a Datapoint to appear clicked.
Please allow me to illustrate it for better understanding.
You can do that using option selectionMode: 'multiple' and selecting appropriate points using setSelection() method. For example:
chart.setSelection([
{row:0, column:1},
{row:0, column:2},
{row:2, column:1},
{row:2, column:2}
]);
Of course, you will have to find out points which correspond to defined threshold. See example at jsbin.
Update: example with DataView.
