Tag: scichartjs

Looking into https://www.scichart.com/documentation/js/current/typedoc/classes/scichartverticalgroup.html I see I can add surfaces to the group, but what about removing them?

I’ve constructed a problematic codepen to show a potential issue:

Any reason for not being able to remove surfaces from the group?

Thanks!

I am having problem instantiating SciChart.js within a specific project and was hoping you might be able to help. To provide context I can run SciChart fine in simple projects and I suspect that I have a webpack issue.

When running a simple graph instantiation such as –

import React, { useEffect } from "react";
import ReactDOM from "react-dom";
import { SciChartSurface } from "scichart/Charting/Visuals/SciChartSurface";
import { NumericAxis } from "scichart/Charting/Visuals/Axis/NumericAxis";

export function MipsGraph(props) {
    useEffect(() => {       
        initSciChart();
    });

    return (
        <div id="depthGraph" style={{height: "100%"}} ></div>
    );
}

async function initSciChart() {
    const { sciChartSurface, wasmContext } = await SciChartSurface.create("depthGraph");

    const xAxis = new NumericAxis(wasmContext);
    const yAxis = new NumericAxis(wasmContext);

    sciChartSurface.xAxes.add(xAxis);
    sciChartSurface.yAxes.add(yAxis);
}

I see the following error

Uncaught (in promise) RuntimeError: abort(TypeError:
WebAssembly.instantiate(): Import #0 module=”env” error: module is not
an object or function). Build with -s ASSERTIONS=1 for more info.

and the warning –

wasm streaming compile failed: TypeError: WebAssembly.instantiate():
Import #0 module=”env” error: module is not an object or function

The warning is raised at line 7544 (after pretty print in chrome dev tools) of scichart2d.js?formatted at a line calling WebAssembly.instantiateStreaming(e,d). both e and d have values.

Debugging originally led me to believe that there was an issue finding the scichart2d.wasm file however network traffic clearly shows the file being fetched.

Any ideas?
