I want to add a point in value ex: 800000 become 800.000 when the pointer is near the bar chart
This is an example chart that I made:
here is the documentation on making a tooltip in chart.js:
https://www.chartjs.org/docs/latest/configuration/tooltip.html
you can add functions to tooltips.callbacks to calculate the title, data etc displayed in the tooltip. Then, with JavaScript's NumberFormat https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat you ought to be able to achieve the look you want.

I'm using Chart.js to build a radar chart. I have seven datasets grouped by color as seen in the image below:
I would like to place the dataset labels outside of the chart, in the center of each dataset sector (at the crosses in the image). Does anyone know if this is possible?
You could probably basically accomplish this by doing roughly the following:
Specify a non-empty label only where you'd like the group label to appear (e.g. for every sixth datapoint or something similar)
Then set the tooltips.callbacks.label option to return the label for each point so that they still appear in the tooltip as they originally would
I have an ASP.NET web forms application which uses DevExpress's bar chart controls. In the below side-by-side bar chart:
I needed to show some extra information apart from traditional x and y argument-values using series point's {HINT} pattern (Hospital Admissions: 130, (65%)) - as per the image.
Now, I need to show it in the bar itself. Like the control shows by-default for Stacked bar charts:
How do I push the Tool tip hint data to be shown inside the data bars?
Any suggestions, kind folks?
It is possible to access the current data row directly when handling the CustomDrawSeriesPoint event. Cast the e.SeriesPoint.
Tag property to the corresponding type (e.g., DataRowView). This should make it possible to update the SeriesPoint label text.
You can find a small sample project that illustrates this approach in the Chart Series Label from a dataset column that is not part of the series ticket.
I'm trying to implement highlight for a single section of line chart while hovering over this section. Under section I mean space between (in my case) vertical lines, which are representing separate date intervals depending on chart zoom level. The chart itself has dynamic data, which is being pulled from an endpoint with more detailed data, depending on date interval zoomed in.
During investigation I've found a plotBands property of x/yAxis. But the thing is, that this property only allows to set each plotBand manually.
So the question is, if there is something that will help me to do automatic creation of plotBands or similar hoverable/clickable stuff, for each separate time "interval"?
you can set the TestValue dynamically according to your needs and use something like this JSFiddle:
plotBands: [{
color: '#FCFFC5',
from: ($.TestValue)+1,
to: ($.TestValue)+2
},...]
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"
}
};
Jsfiddle example here.
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.
