XY Chart, Fixed Y Axis

Ignition
,
1

I made an XY Chart that has some zones marked (I have it configured the same way as the example from the " XY Chart Example - Line Chart Target Area" from the Ignition Manual). After I made the top red area, the chart moved up to show 40-50, which I do not need.

Is there anyway to fix the chart, so it will only show certain numbers on the Y axis? I want it to always display 0-40 even if a point is off the chart.

yAxes.0.value.range.max : ...
yAxes.0.value.range.min : ...
yAxes.0.value.range.useStrict : true

I'd tone down the color bands so that your data stands out. The human eye just needs a hint for the pass band. The opacity value is handy for that.

  • Create a custom prop areaOpacity on the chart - or on the view - or as a session variable if you want it applicable everywhere.
  • Add a Property Binding to each series.x.line.appearance.fill.opacity to the custom prop.

Now you can adjust them all in one place.
