Clear chart

[ziggyParticipant]

Hi,

Is there a function to clear chart?

Thanks and regards.

Hi Karen,

There is no built in function, but like a workaround you can set 0 for all values an then to update.

Hi Ivailo,

What do you mean 0 for all values?

Like this?

$('#jqxGraphViewProcessAlign').jqxChart({
                    source: 0,
                    xAxis:
                    {
                        type: 0,
                        baseUnit: 0,
                        dataField: 0,
                        valuesOnTicks: 0,
                        unitInterval: 0,
                        tickMarks: 0,
                        axisSize:0,
                        minValue: 0,
                        maxValue: 0,
                        labels:
                        {
                            angle: 30,
                            horizontalAlignment: 'left',
                            verticalAlignment: 'center',
                            rotationPoint: 'left',
                            offset: { y: -30 },
                            formatFunction: function(value)
                            {
                                return  $.jqx.dataFormat.formatDate(value, 'dd-MMM-yyyy HH:ss');
                            }
                        }
                    }
                });

Hi Karen,

Set your data source with 0 values.

Hi Ivailo,

When I set the source to an empty array, I get the following error:

Error: Invalid value for <rect> attribute y="NaN"

Is there a cleaner way to clear the charts? An example would be a great help.

Thanks!

Hi Karen,

Set the valus of your data source like this.

var data = [{
         a: 0,
         b: 0,
         c: ...
     }]

Then update.
Here is a bit modified update demo for visualization.

Hi Karen,

You can also try:

   $('#chartContainer').jqxChart('seriesGroups', []);
