I'm using the "ui.Chart.Image.Regions" type to produce three graphics for three different SENTINEL-2 images, with EVI index values.

I would like to normalize the horizontal label (the X label) so they look the same on all three graphs.

I used the "xLabels" property of this chart type by putting the values xLabels = [0.0, 0.5, 1.0],

however I got the following error message:

Error generating chart: The length of the xLabels list should equal the number of bands in the image. Found 1 bands and 3 elements in xLabels. ".

Here is my code: EVI INDEX


They look the same on the horizontal axis. I guess you want to set predefined vertical labels? You can set that under setOptions({vAxis}) as follows:

vAxis: {maxValue: 1, ticks: [0.0, 0.5, 1.0]}
