• Past release notes

February 2020 (v5.21)

• The Line chart arrow and filledarrow tickmark styles now respect the tickmarksSize property.
• The SegmentedMeter variation of the Pie chart now has a valueDecimals property.
• Fixed a bug with the adjustable SVG Gauge chart and Firefox - it wasn't fetching the cursor position correctly so adjusting didn't work correctly.
• Fixed a bug with the Pie/Donut 3D variants that meant that the shadow wasn't being drawn correctly.
• Lots of Internet Explorer 11 related bugs were fixed.
• When using the drawing API X axis and Y axis objects you should be aware that the color properties have changed. They're no longer called colors - they're now called xaxisColor and yaxisColor and they're not arrays but a single color.
• All of the margins have been synchronised at 35. This may cause your charts to shift a little if you upgrade but you can just set them back to what you want them to be with the marginLeft marginRight marginTop and marginBottom properties.
• If you use the axes property to turn off both the X and Y axes you will now need to use both the xaxis and yaxis properties.
• The Bar, Horizontal Bar, Line, Gantt, Scatter and Waterfall charts and the drawing X axis now all use a common RGraph.drawXAxis() function. It is, quite naturally, a large function - but also quite versatile because it supports all kinds of different options. As a result some chart types have new options for their X axis.
• The Bar, Horizontal Bar, Line, Gantt, Scatter and Waterfall charts and the drawing API Y axis now all use a common RGraph.drawYAxis() function. Again, it's a large function - but also quite versatile because it supports all kinds of different options. As a result some chart types have new options. Notably, the yaxisLabels option has been changed to the yaxisScale option, which turns on and off the Y axis scale labels.
• The innerHTML property that was used in a few places in the RGraph.common.core.js has been changed to the faster insertAdjacentHTML() function.
• The property yaxisScaleZerostart has been removed. The scale now always starts with zero.
• The documentation for the canvas Scatter chart has been bolstered with clearer information about the format of the data array.
• A new feature which is coming in the next version of RGraph (which will be 5.22) and which has already been partially implemented in the Bar chart is tooltip templates. There's a demo in the download archive called bar-tooltip-templates.html which demonstrates this exciting (!) new feature. You can read a little about it on the tooltips feature documentation page .
