Hi Alexandr

I think the message is quite self explanatory

getNativeXValues is invalid for heatmap type series. Try getting or setting zValues instead

See the property here zValues. This is a two dimensional array

JavaScript Uniform Heatmap Documentation

There is a section in the page above showing how to update values in a heat map

import { UniformHeatmapDataSeries } from "scichart/Charting/Model/UniformHeatmapDataSeries";
import { zeroArray2D } from "scichart/utils/zeroArray2D";

// Create an empty 2D array of size height & width
const initialZValues: number[][] = zeroArray2D([height, width]);
// Create a Heatmap Data-series. Pass the heatValues as a number[][] to the UniformHeatmapDataSeries
const heatmapDataSeries = new UniformHeatmapDataSeries(wasmContext, 0, 1, 0, 1, initialZValues);

// ...

// Later, update the data
initialZValues[5][6] = 123.4;

// Tell SciChart the data has changed
heatmapDataSeries.notifyDataChanged()

// You can also load an entirely new array with the function UniformHeatmapDataSeries.setZValues
const newZValues: number[][];
heatmapDataSeries.setZValues(newZValues);

Try this?

Best regards
Andrew
