# Line Chart props ### Basic props | Prop | Type | Description | Default value | | ------------------- | -------------- | --------------------------------------------------------------------------------------- | ------------------- | | data | Array of items | An item object represents a point in the line chart. It is described in the next table. | \_ | | data2 | Array of items | Second set of dataPoint for the second line | \_ | | data3 | Array of items | Third set of dataPoint for the third line | \_ | | width | number | Width of the Bar chart | width of the parent | | height | number | Height of the Bar chart (excluding the bottom label) | 200 | | maxValue | number | Maximum value shown in the Y axis | 200 | | noOfSections | number | Number of sections in the Y axis | 10 | | stepValue | number | Value of 1 step/section in the Y axis | 20 | | stepHeight | number | Height of 1 step/section in the Y axis | 20 | | spacing | number | Distance between 2 consecutive bars in the Bar chart | 20 | | backgroundColor | ColorValue | Background color of the Bar chart | \_ | | disableScroll | Boolean | To disable horizontal scroll | false | | showScrollIndicator | Boolean | To show horizontal scroll indicator | false | --- **Alert!**\ These props are correlated: 1. maxValue 2. noOfSections 3. stepValue They must follow the relation: ```js maxValue = noOfSections * stepValue; ``` So, all the three must be used together. Using any 1 or 2 of them may produce absurd results --- ### Item description | Key | Value type | Description | | --------------------- | ---------- |
