Max Min Limit setup in custom visual

AakashMarasini — Fri, 29 Sep 2023 06:44:52 GMT

Hi Developers!

I am building a custom visual and added the Max Area height for x axis. Now i want to set the min and max value to it. I have tried putting those values in capabilities.json file and in setting.js file but didnot work.

In setting.js file, My code for maxAreaHeight. it shows error while adding max and min to it.

public maxAreaHeightX = new formattingSettings.Slider({ name: "maxAreaHeightX", displayName: "Max Area Height", value: 20 });

And the object for this in capabilities.json looks like as below:

"maxAreaHeightX": { "displayName": "Max Area Height", "type": { "integer": true } }

I have set the max and min value of 30 and 10 respectively. But in the formatting slider the value is showing 0 to 100.Also In the slider, i want the value starting from 10 to 30.

let maxAreaHeightPercentageX = this.visualSettings.xAxis.maxAreaHeightX.value ; maxAreaHeightPercentageX = Math.min(30, Math.max(10, maxAreaHeightPercentageX));

I don't know if you already got it, but I managed to do it with something like this (in your settings.ts file):

import powerbi from "powerbi-visuals-api"; ... class MyMaxValidator implements powerbi.visuals.MaxValidator<number> { type: powerbi.visuals.ValidatorType.Max; value: number; constructor(max: number) { this.value = max; } } class MyMinValidator implements powerbi.visuals.MinValidator<number> { type: powerbi.visuals.ValidatorType.Min; value: number; constructor(min: number) { this.value = min; } } ... public maxAreaHeightX = new formattingSettings.Slider({ name: "maxAreaHeightX", displayName: "Max Area Height", value: 20, options: { maxValue: new MyMaxValidator(30), minValue: new MyMinValidator(10) } });

@ewaghabi Thanks a lot! The issue was stayed unsolved. Now, it works with the above code.

Thanks Again!

Easier way to do this is :

public maxAreaHeightX = new formattingSettings.Slider({ name: "maxAreaHeightX", displayName: "Max Area Height", value: 20, options: { maxValue: { type: powerbi.visuals.ValidatorType.Max, value: 30 }, minValue: { type: powerbi.visuals.ValidatorType.Min, value: 10 } } });
