The above example shows you how to create LineChart using ChartJs package. In this example, for purpose of chart demonstration only, we do use mock-up data from array. As you can see, the KoolReport's widget in general support dataSource could be DataStore, Process, DataSource or even simple array.
This example shows how to build a line chart with the y-axis range set using the suggestedMin and suggestedMax properties. The data minimum and maximum used for determining the ticks is Math.min(dataMin, suggestedMin) and Math.max(dataMax, suggestedMax).
For example:
...
"scales" => array(
"yAxes" => array(
array(
"ticks" => array(
"suggestedMin" => 10,
"suggestedMax" => 50,
)
)
)
)
...
