stacked bar chart using echarts

[alexjv89]

. key things required

• x axis filtering using the slider
• y axis, stack selection using checkbox
• top sum number for each stack.

Use this color pallete. the bar charts can have only one of these color. Restrict the option for the users so that they can pick a color quickly.. Maybe name these colors as green_1, green_2,green_3, green_4, red_1 etc. The color can be overridden by specifying the hex values.
