Scatter chart issue: The xaxisScaleFormatter property is not working as expected
Posted by sho at 11:20 on Friday 6th September 2024 [link]
"Dear RGraph Support Team,
I hope this message finds you well. I am currently working on a project that involves using the RGraph Scatter Chart, and I encountered an issue with the xaxisScaleFormatter functionality. Despite properly configuring the formatter function, it does not appear to be triggered during the graph rendering, and as a result, the X-axis labels are not being formatted as expected.
Here are the steps I have taken to resolve the issue:
Verified that xaxisScaleMin and xaxisScaleMax are set correctly.
Updated to the latest version of RGraph (6.18).
Simplified the graph configuration to isolate the issue.
However, the problem persists. I would greatly appreciate any guidance or suggestions on how to address this issue. If this is a bug, I hope this report can help improve the library.
Thank you for your time and assistance.
Best regards,
```

I've taken your configuration, massaged it a little and put it here:
https://www.rgraph.net/tests/canvas.scatter/xaxisScaleFormatter.html
You were using an old format for the xaxisScaleFormatter function so I've updated that. Here's the source code for the chart that's in that page:
scatter = new RGraph.Scatter({
id: "cvs",
data: rawData,
options: {
marginLeft: 50,
marginRight: 50,
marginTop: 50,
marginBottom: 50,
tooltipsFormattedKeyColors: ["black", "red"],
tooltipsCss: {
fontSize: "16pt",
boxShadow: "",
textAlign: "left",
},
xaxisScale: true,
xaxisScaleMax: 1.25 * abs_max,
xaxisScaleMin: -1.25 * abs_max,
xaxisScaleDecimals: 2,
xaxisTickmarks: false,
xaxisLabelsCount: 5,
xaxisScaleFormatter: function (opt)
{
return parseFloat(opt.number).toFixed(3);
},
yaxisScaleMax: 1.25 * abs_max,
yaxisScaleMin: -1.25 * abs_max,
yaxisScaleDecimals: 2,
backgroundGridColor: "#eee",
textSize: 16
},
}).draw();
