How to limit the multiplier of enlargement and reduction when enlarging and reducing

Hi Huang.

I’m not sure that I understand what you mean by limiting the multiplier of enlargement and reduction.

If you want to adjust scale factor of PinchZoomModifier you can use ScaleFactor property ( by default it has 2f value ). You can reduce it to decrease zoom speed and vice versa:

sciChartBuilder.newModifierGroup()
               .withPinchZoomModifier().withScaleFactor(1.5f).build()
               .build();

If you want to restrict zoom on some axis then you can use one of properties provided by axis such as MinimalZoomConstrain, MaximumZoomConstrain or VisibleRangeLimit:

    xAxis.setMinimalZoomConstrain(0.001d);
    xAxis.setMaximumZoomConstrain(1000d);
    xAxis.setVisibleRangeLimit(new DoubleRange(0d, 10000d));

Hope this will help you!

Best regards,
Yura
