Hi all,

I would like to ask how to modify the label of the OHLC Chart in Android.
For example, in the attached screenshot, how to change the label “Highest” to “High” ? Thanks.

Hi Ray,

To achieve that you need to create custom SeriesInfoProvider, override getSeriesTooltipInternal method and return
Custom tooltip inside in it. Please take a look at our documentation below:

Please take a look at the custom series info provider and custom tooltip code below, which demonstrates how to do that:

private static class CustomOhlcSeriesInfoProvider extends DefaultOhlcSeriesInfoProvider {
    protected ISeriesTooltip getSeriesTooltipInternal(Context context, OhlcSeriesInfo seriesInfo) {
        return new CustomOhlcSeriesTooltip(context, seriesInfo);

    private static class CustomOhlcSeriesTooltip extends OhlcSeriesTooltip {
        public CustomOhlcSeriesTooltip(Context context, OhlcSeriesInfo seriesInfo) {
            super(context, seriesInfo);

        protected boolean internalUpdate(OhlcSeriesInfo seriesInfo) {
            final StringBuilder sb = new StringBuilder();
            sb.append(String.format("Open CHANGED: %s", seriesInfo.getFormattedOpenValue()));
            sb.append(String.format("High CHANGED: %s", seriesInfo.getFormattedHighValue()));
            sb.append(String.format("Low CHANGED: %s", seriesInfo.getFormattedLowValue()));
            sb.append(String.format("Close CHANGED: %s", seriesInfo.getFormattedCloseValue()));


            return true;

all you need to do, is to set SeriesInfoProvider to your OHLC series like so:

  candlestickRenderableSeries.setSeriesInfoProvider(new CustomOhlcSeriesInfoProvider());

Hope this helps.
Best regards.
