# PlotIndexGetInteger

The function sets the value of the corresponding property of the corresponding indicator line. The indicator property must be of the int, color, bool or char type. There are 2 variants of the function.

Call indicating identifier of the property.

```
int  PlotIndexGetInteger(
   int  plot_index,        // plotting style index
   int  prop_id,           // property identifier
   );

```

Call indicating the identifier and modifier of the property.

```
int  PlotIndexGetInteger(
   int  plot_index,        // plotting index
   int  prop_id,           // property identifier
   int  prop_modifier      // property modifier
   )

```

Parameters

plot_index

[in]  Index of the [graphical plotting](/en/docs/constants/indicatorconstants/drawstyles#enum_draw_type)

prop_id

[in] The value can be one of the values of the [ENUM_PLOT_PROPERTY_INTEGER](/en/docs/constants/indicatorconstants/drawstyles#enum_plot_property_integer) enumeration.

prop_modifier

[in]  Modifier of the specified property. Only color index properties require a modifier.

Note

Function is designed to extract the settings of drawing of the appropriate indicator line. The function works in tandem with the function [PlotIndexSetInteger](/en/docs/customind/plotindexsetinteger) to copy the drawing properties of one line to another.

Example: an indicator that colors candles depending on the day of the week. Colors for each day are set in a programmatically.
