@scompliance,

Zooming across charts is not working after switching the dashboard as you are resetting the chart-references on switching the charts. Instead setting the selectedDashboard only if the value has changed & adding chart-references only once should work fine for you. Please find the updated code-snippet below.

Change selectedDashboard only if the value has changed.

const handleDashboardChange = (event) => {
  if (event.target.value !== selectedDashboard) {
    setSelectedDashboard(event.target.value);
  }
};

Add chart-ref only once.

<CanvasJSChart
  key={index}
  options={options}
  onRef={(ref) => {
    if (ref && !chartsRef.current.includes(ref)) {
      chartsRef.current.push(ref);
    }
  }}
/>

Please take a look at this updated Stackblitz for working example.

@scompliance,

Changing legend line dash type is not possible as of now. However, you can achieve rendering broken line in legend by setting the legendMarkerColor to white (same as chart background) and legendMarkerType to triangle. Please take a look at this JSFiddle for an example of the same.

@scompliance,

chart.container / chart.get(“container”) is accessible & seems to be working fine. Can you kindly share a JSFiddle (or Sample project over Google Drive / Onedrive) reproducing the issue so that we can run it at our end to understand the scenario better and help you out?

@scompliance,

To ensure that the chart adjusts to the updated height, you can use a key prop on the CanvasJSChart component. When the height state changes, updating the key prop will force React to treat the component as a new one, which will apply the updated height. Please find the updated code-snippet below.

return (
  <div>
    <CanvasJSChart
      options={options}
      containerProps={{ width: "100%", height }}
      key={height}  // This forces re-mount when the height changes
    />
  </div>
);

Another option is to directly update the chart’s height using the set method – chart.set("height", 100). Please refer to this Codesandbox link for updated code.

@taoufiq,

Thank you for reporting the issue and providing the use-case. We will investigate this further and work on a fix for future versions. Your feedback is greatly appreciated!

@ayankhan21,

Are you referring to the axis ticks? If so, you can remove the hyphen next to the axis labels by setting the tickLength to 0. This will hide the ticks completely. If you’re referring to something else, could you please share a pictorial representation so that we can understand the scenario better and help you out?

Adam Evans,

Updating legendText on hovering over the datapoint should work fine as per your requirements. Please find the code-snippet below.

mouseover: onMouseover(e){	
    e.dataSeries.legendText = (e.dataSeries.dataPoints[e.dataPointIndex].x + ": " + e.dataSeries.dataPoints[e.dataPointIndex].y).toString();
    e.chart.render();
}

Please take a look at this JSFiddle for an example of the same.

@discovered1086,

The chart is currently taking 100% of the container’s width and seems to be working fine. Could you please create a JSFiddle (or Stackblitz for React/Angular apps) that reproduces the issue & share it with us so that we can look into the code, understand the scenario better and help you out?

@dunhamcd,

In a logarithmic scale, the axis labels represent powers of logarithmBase – defaults to 10 (1, 10, 100, etc.) instead of linear increments due to how logarithmic values work. Using a linear scale may better suit your needs if you prefer different label increments like 1, 2, 3,…

@scompliance,

In case of React Charts, you can set the height and width of the chart-container by passing it as containerProps as shown in the code-snippet below.
<CanvasJSChart options={options} containerProps={{ width: '100%', height: '300px' }} />

Please refer to React Charts documentation for more information.

@scompliance,

You can change the thickness of the line by updating endValue within rangeChanged event as shown in code-snippet below.

rangeData[1].endValue = new Date(rangeData[1].startValue.getTime() + (e.chart.axisX[0].viewportMaximum - e.chart.axisX[0].viewportMinimum) / e.chart.axisX[0].bounds.width * 3);

Please take a look at this updated JSFiddle for a working example of the same.

@scompliance,

You seem to have missed out updating your code, code related to accepting stripline bounds from chart is missing in the Stackblitz you have shared. Updating it seems to be working fine. Please take a look at this updated Stackblitz for working example.

Also, in case of range-area chart adding range-area series with 2 datapoints with minor difference in the time component should work fine for single value as-well. Please take a look at this updated JSFiddle.

@scompliance,

You seem to have replaced App.jsx code with Chart.jsx code in the Stackblitz link that you have shared. Either you can use stripline in this case as shown in the previous reply or you can use range-area chart instead of stripline. The advantage of using range-area chart in this scenario includes letting library to show tooltip, mouse-events & showing series in legend. Please take a look at this JSFiddle for an example of the same.

@scompliance,

Tooltip for stripline is not available as of now. In the current case of zooming / panning, the solution shared earlier can be improved further by checking if the current-mouse coordinate is within the plotarea bounds or not along with existing conditions as shown in the code-snippet below.

xPos >= stripLine.chart.plotArea.x1 && xPos <= stripLine.chart.plotArea.x2 && yPos >= stripLine.chart.plotArea.y1 && yPos <= stripLine.chart.plotArea.y2

Please take a look at this updated Stackblitz for working code.

@scompliance,

Checking if the startValue & endValue lies within the axis range should work fine in this case. Please find the code-snippet for the same below.

stripLine.startValue < stripLine.chart.axisX[0].viewportMaximum && stripLine.endValue > stripLine.chart.axisX[0].viewportMinimum

Please take a look at this updated Stackblitz for working code.
