I am using Dojo Charts to create some line graphs, and this is how the chart looks,
this id chartData: 0,0,0,0,65,223
And when I create the graph using Chart.js, this is how it is rendered
Ignore the x-axis and other things, If we look at the y-axis, the values are rounded in chart.js, looks much nicer when compared to dojo charts.
Is there an option to achieve the same in dojo charts?
Try adjusting majorTickStep, or optionally also set minorTickMarks to true and adjust minorTickStep as well.
See http://dojotoolkit.org/reference-guide/1.10/dojox/charting.html#enabling-and-disabling-tick-marks and "Axis Stepping" two sections later.

I would like change the colors of the slices in an ag-grid Pie Chart. Is it possible? I am using React.

I figured out the solution, which was actually obvious but I was not correctly looking. The API reference lists "fills?: string[]". All set.
I have to build a horizontal bar with chartjs. I already built a few of them but its a bit different. The chart has 2 labels for the yAxis ("Storm Risk", "Ice Risk") and hours for the xAxes. I have to print out for every hour one of these different options with different colors ("Low", "Medium", "Hight") as ye can see in the screenshot attached.
This kind of bar chart usually the values are represented by the length of the bar and its a bit different.
Any suggestion?.
Thanks
The chart you want to implement is a sort of a "heatmap". As of now (Sep. 2018), Heatmap charts are not supported out of the box by Chart.js. However, you can make one out of a stacked bar chart (in this case, probably stacked horizontal bar chart?): make each stack size equal to one another and each item backgroundColor depending on the actual values being represented. Once this is done, you can override ticks and tooltips using with according callbacks. Legend can be implemented by one more bar chart with sample values and colors.
More details can be found in a related GitHub issue: https://github.com/chartjs/Chart.js/issues/4627
Another alternative would be to use a BubbleChart. The strategy would be similar - you would need to make all bubbles same size, but override their colors. However, provided the look in the question, stacked horizontal bar chart will be more suitable.
Another option for those who are still looking is to use chartjs-chart-matrix https://chartjs-chart-matrix.pages.dev/usage.html plugin.
Example of implementation with Chart.js v3: https://www.youtube.com/watch?v=bi04BgvNY6U
I have dynamic pie set and if there are a lot of series then pie get small.
How to set fixed pie chart radius.
A PiePlot grows to fill the space available, so you'll need to give it room to grow. Some possible approaches:
Override getPreferredSize() and use a suitable layout, as shown here among other suggestions.
Display the legend items in an adjacent component, as shown here, leaving the chart alone to fill it's container.
Reposition the legend within the chart, as shown here for the default RectangleEdge.BOTTOM.

This is the main demo:

In the pie I would like to have the description (in the example the Browser name) instead of percentage in the labels. Is it possibile? I found how to set it only for the legend but not in the label inside the pie.
Have you tried to implement the Chart's formatFunction which is used for formatting the Labels?
I'm using a dojo chart to display data in a bubble chart. However, I don't need the axis but if I remove the axis, it screws up the display of the data. I can fudge axis not being there by hiding labels and coloring the lines white but then there's still this large margin on the left and bottom of the chart. How do you make a dojo chart without the axis while still having the min/max set correctly?
chart1.addAxis("x",{ type : 'Invisible' /*, .... */ });
Matthew, if you are still looking to tweak the margins, the solution here:
dojox charting: remove the padding around the chart
worked for me.
