Y-axis labels are gone when majorDelta is set to 0.1

Hi Quyền,

What’s happening is you’ve chosen a major delta that is too small to view all the labels and SciChart is hiding the ones which overlap (which is all of them)

You can disable label overlapping by passing hideOverlappingLabels = false to the axis constructor. This property may also be set dynamically by setting axis.axisRenderer.hideOverlappingLabels.

Try that and let me know if labels show up. If not, we can investigate further.

Best regards
Andrew

Hi Andrew,

I tried to set hideOverlappingLabels to false in the axis constructor. But it doesn’t help and it also caused UI issue when I set the majorDelta to small values (Please check the attached screenshot). Not sure if I have any settings wrong, please check my codes of the axis constructor:

        const yAxis = new NumericAxis(wasmContext, {
                axisTitle: "Power (dBm)",
                axisTitleStyle: {
                    fontSize: CHART_STYLE.AXIS_FONT_SIZE,
                            fontFamily: "sans-serif",
                            fontWeight: "bold"
                },
                labelStyle: {
                           fontSize: CHART_STYLE.LABEL_FONT_SIZE,
                            fontFamily: "sans-serif"
                },
                autoTicks: false,
                majorDelta: specSettings.scale,
                minorDelta: specSettings.scale / 5,
                axisAlignment: EAxisAlignment.Left,
                visibleRange: yAxisNumberRange,
                visibleRangeLimit: yAxisNumberRange,
                zoomExtentsRange: yAxisNumberRange,
                labelFormat: ENumericFormat.Decimal,
                labelPrecision: 2,
                cursorLabelFormat: ENumericFormat.Decimal,
                cursorLabelPrecision: 2,
                drawMajorBands: false,
                hideOverlappingLabels: false,
    });

The value of specSettings.scale above is limited to 0.1 to 20. When it’s equal to 0.1, the y-axis labels will be gone even hideOverlappingLabels is set to false.
