I have a Google script to automatically adjust the 'Max' Value for the Vertical Axis based on the max value from a column in the source data. This part is working, but, the number format keeps changing to a date.
How it's outputting:
How I want it to output, after updating the V Axis:
My Script:
> function updateChartMax() {> // Reference the sheet containing the data> var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();> var sourceSheet = spreadsheet.getSheetByName("Graph Data"); // Replace with your sheet name> > // Get the range of data from column O (15th column), starting from row 2> var dataRange = sourceSheet.getRange(2, 15, sourceSheet.getLastRow() - 1); > var columnData = dataRange.getValues(); > var mat = Math.max(...columnData.flat()); // Find the maximum value in the column> > // Reference the sheet containing the chart> var chartSheet = spreadsheet.getSheetByName("Manage"); // Replace with your chart sheet name> var chart = chartSheet.getCharts()[0]; // Get the first chart on the sheet> > if (chart) { // Ensure the chart exists before modifying> chart = chart.modify()> .setOption('vAxes.0.viewWindow.max', mat) // Set the max value dynamically> .setOption('vAxes.0.viewWindow.min', 0) // Set the min value to 0> .build();> chartSheet.updateChart(chart); // Apply the changes to the chart> } else {> SpreadsheetApp.getUi().alert("No charts found on the sheet.");> }> }I've tried changing the number format in the source data, using =to_pure_number and tried multiple different formatting options with no luck.
