Waterfall Chart
This chart type belongs to PowerCharts XT.
A waterfall (cascade) chart is a special type of column chart that is used to show how an initial value is increased and decreased by a series of intermediate values, leading to a final value.
Let's create our first waterfall chart which will showcase the profit and loss analysis.
To create a waterfall chart follow the steps given below:
In the JSON data, set the attributes and their corresponding values in
"<attributeName>": "<value>"
format.Specify the chart type using the
type
attribute. To render a waterfall chart, setwaterfall
.Set the container object using
renderAt
attribute.Specify the dimension of the chart using
width
andheight
attributes.Set the type of data (JSON/XML) you want to pass to the chart object using
dataFormat
attribute.
For a detailed list of attributes, refer to the chart attributes page of waterfall chart.
The waterfall chart thus rendered looks like this:

Customize Colors for the Columns
By default, every data plot in a waterfall chart is rendered using a different color irrespective of whether it is a positive or a negative column. You can, however, customize the chart to show distinct colors for the positive and negative columns.
To customize the chart to show distinct colors for the positive and negative columns, follow the steps given below:
To set the color for the positive data plots on the chart, specify the hex color code to
positiveColor
attribute.To set the color for the negative data plots on the chart, specify the hex color code to
negativeColor
attribute.
Refer to the code given below:
{
"chart": {
"positiveColor": "#1aaf5d",
"negativeColor": "#c02d00"
},
}

Show/Hide Sum Columns
Show/Hide a Cumulative Sum Column
A cumulative sum column is something that will show you the sum of all columns to its left. To see the sum of all columns to its left, set the isSum
attribute as 1
.
Refer to the code given below:
{
"chart": {
"showSumAtEnd": "0"
},
"data": [
{
...
"issum": "1",
...
}]
}

Show/Hide a Non-cumulative Sum Column
A non-cumulative sum column is one that shows the sum of all the columns to its left but after the last cumulative sum column. To show the non-cumulative use the following attributes:
Set the
isSum
attribute to1
to render a column displaying sum of all the previous data values.Set the
cumulative
attribute to0
to render non-cumulative columns.
Refer to the code below:
{
"chart": {
...
},
"data": [
{
"label": "Promotion Costs",
"value": "-86000"
},
{
"label": "Total Costs",
"issum": "1",
"cumulative": "0"
}
]
}

In the above chart, the 'Total Costs' column is a non-cumulative sum column.
Show/Hide a Total Sum Column
By default, a column that represents the sum of all the values plotted on the chart - the total sum column - is shown in the waterfall chart. You can, however, opt not to show this column. In the waterfall chart shown above, the 'Total Profit' column is the total sum column.
To do so, the following attributes are used:
Set the
showSumAtEnd
attribute to0
to hide the column of total sum.Specify the name of the column of total sum using the
sumLabel
attribute.
Refer to the code below:
{
"chart": {
"sumlabel": "Total {br} Profit",
"showSumAtEnd": "0"
},
}

Customize Connectors
Waterfall charts, by default, display connector lines between two consecutive columns which helps in indicating the nature of transition (positive or negative). You can customize the cosmetic properties of these connector lines.
To customize the cosmetic properties of the connector lines, follow the steps given below:
Set the
showConnectors
attribute to0
to hide the connectors.Specify the
connectorColor
attribute to set the hex color code for the connector lines.Specify the
connectorAplha
attribute to set the transparency for the connector lines. This attribute takes values between0
(transparent) and100
(opaque).Specify the
connectorThickness
attribute to set the thickness of the connector lines.To render the connector lines as dashed lines, set the
connectorDashed
attribute to1
.Set the length of the dash (for dashed connector lines), using
connectorDashLen
attribute.Set the gap between each dash (for dashed connector lines), using
connectorDashLen
attribute.
Refer to the code given below:
{
"chart": {
"connectorColor": "#660000",
"connectorAlpha": "50",
"connectorThickness": "3",
"connectorDashed": "1",
"connectorDashLen": "5"
"connectorDashGap": "2"
},
}
