ChartSetDouble

Sets a value for a corresponding property of the specified chart. Chart property should be of a double type. The command is added to chart messages queue and will be executed after processing of all previous commands.

Parameters

chart_id

[in]  Chart ID. 0 means the current chart.

prop_id

[in]  Chart property ID. Can be one of the ENUM_CHART_PROPERTY_DOUBLE values (except the read-only properties).

value

[in] Property value.

Return Value

Returns true if the command has been added to chart queue, otherwise false. To get an information about the error, call the GetLastError() function.

Note

The function is asynchronous, which means that the function does not wait for the execution of the command, which has been successfully added to the queue of specified the chart. Instead, it immediately returns control. The property will only change after the handling of the appropriate command from the chart queue. To immediately execute commands from the chart queue, call the ChartRedraw function.

If you want to immediately change several chart properties at once, then the corresponding functions (ChartSetString, ChartSetDouble, ChartSetString) should be executed in one code block, after which you should call ChartRedraw once.

To check the command execution result, you can use a function, which requests the specified chart property (ChartGetInteger, ChartGetDouble, ChartSetString). However, note that these functions are synchronous and wait for execution results.
