# GraphPlot

Functions for quick curve plotting.

Version for plotting a single curve using Y coordinates.

```
string  GraphPlot(
   const double     &y[],                  // Y coordinates
   ENUM_CURVE_TYPE  type=CURVE_POINTS      // curve type
   )

```

Note

Y array indices are used as X coordinates for the curve.

Version for plotting a single curve using X and Y coordinates

```
string  GraphPlot(
   const double     &x[],                  // X coordinates
   const double     &y[],                  // Y coordinates
   ENUM_CURVE_TYPE  type=CURVE_POINTS      // curve type
   )

```

Version for plotting two curves using X and Y coordinates

```
string  GraphPlot(
   const double     &x1[],                 // X coordinates
   const double     &y1[],                 // Y coordinates
   const double     &x2[],                 // X coordinates
   const double     &y2[],                 // Y coordinates
   ENUM_CURVE_TYPE  type=CURVE_POINTS      // curve type
   )

```

Version for plotting three curves using X and Y coordinates

```
string  GraphPlot(
   const double     &x1[],                 // X coordinates

   ENUM_CURVE_TYPE  type=CURVE_POINTS      // curve type
   )

```

Version for plotting a curve using CPoint2D points coordinates
