title: is_chart_data_changed method second_title: Aspose.Cells for Python via .NET API References description: type: docs weight: 80 url: /aspose.cells.charts/chart/is_chart_data_changed/ is_root: false

is_chart_data_changed(self) {#}

Detects if a chart's data source has changed.

Returns

Returns true if the chart has changed otherwise returns false

def is_chart_data_changed(self):
    ...

Remarks

The method detects the changes in the chart's data source before rendering the chart to image format. At first Chart.toImage call, the chart source data (e.g. XValuesParseData, ValuesParseData) will be recorded. Before calling the Chart.toImage method again, call IsChartDataChanged method to check if Chart needs re-rendering.
