The numeric axis in our app weirdly displays the range from -2000 until 8000, even if it has or hasn’t got data series appended to it. I tried setting the VisibleRange and VisibleRangeLimit when creating the axis, but still no results. Here’s a piece of the code:

new SCINumericAxis
{
   AxisAlignment = SCIAxisAlignment.Left,
   AxisId = "axis_id",
   TextFormatting = " 0%",
   VisibleRangeLimit = new SCIDoubleRange(-30, 100),
   VisibleRange = new SCIDoubleRange(-30, 100)
};

The Y values that we have are doubles, example:

[0]: 98.26171875
[1]: 0
[2]: NaN
[3]: 98.26171875
[4]: 0
[5]: NaN
[6]: 78.203125
[7]: NaN
[8]: 38.96484375
[9]: NaN
[10]: 98.28125
[11]: 0
[12]: NaN
[13]: 68.22265625
[14]: 0

So just by looking at the values, we should have a data range from 0 to 100, but I think somehow it messes up the conversion and ends up with ridiculously large numbers. I’m not doing any additional operations on the data, the printed data above is the data from the XyDataSeries. The Y type is Double, the YMin is 0, the YMax is 98, but still ends up drawing the values until 10000.

our app is about Futures. we will buy license for IOS and Android.

we found some question.

so we need show very small values, like Euro exchange’s values will be from 1.1981 to 1.2008.
its Tick Size is 0.0001 .

but we use LogarithmicNumericAxis with OhlcDataSeries<Date, Double> , surface still linear scale.

other question.
how to custom LogarithmicNumericAxis’s “TextFormatting” like “$0.0000”

I have a chart that has Real Time updates. I would like to create a custom legend modifier to display the latest value in the legend as well as other information. Is it possible to do this and if so where can I find an example?
