Configuring Spark Column Chart
FusionCharts Suite XT allows you to customize several cosmetic and functional properties for the spark column chart.
In this section, you will be shown how you can:
-
Configure period blocks
-
Configure the high and low columns
-
Add trend-lines/trend-zones
-
Configure hover effects
Configuring Period Blocks for the Chart
You can show period blocks on the chart using colored bands. This helps you easily interpret periods on the chart.
A spark column chart rendered with a period block of three months looks like this:
{
"chart": {
"theme": "fint",
"caption": "Revenue by Month",
"subcaption": "Last year",
"subCaptionFontSize": "11",
"numberPrefix": "$",
"highColor": "#6baa01",
"lowColor": "#e44a00",
"chartBottomMargin": "30",
"periodlength": "3",
"periodcolor": "#cccccc",
"periodalpha": "50"
},
"dataset": [
{
"data": [
{

</html>Given below is a brief description of the attributes used to configure a period block:
| Attribute Name | Description |
|---|---|
|
It is used to specify the number of data points that a period block will encapsulate. For our example, we will set this value to 3. |
|
It is used to specify the hex code of the color that will be used to render the period block, e.g. #555555. |
|
It is used to specify the transparency of the period block. This attribute takes values between 0 (transparent) and 100 (opaque), e.g. 60. |
Configuring the High and Low Columns
By default, the spark column chart highlights, using a default color, the highest and lowest data plots and also shows their value. You can, however, configure the colors for the highest and lowest columns based on your requirement.
A spark column chart with the color of the high and low columns configured looks like this:
{
"chart": {
"theme": "fint",
"caption": "Revenue by Month",
"subcaption": "Last year",
"subCaptionFontSize": "11",
