Vvidget Server ► Dictionary ► Point Map Chart
This section explains how to form an input string for a Point Map Chart such as these:
| Format | |
| chart_subtype=0 (Rectilinear) | chart_subtype=1 (X-Log) |
The input string has this form:
chart_type=7&chart_subtype=0&chart_format_type=0&title=string&x_title=string&y_title=string&grid_x_length=N&grid_x_minimum=x0&grid_x_maximum=x1&grid_y_length=M&grid_y_minimum=y0&grid_y_maximum=y1&color_map_1_type=CMT1&color_map_2_type=CMT2&color_map_1_length=CML1&color_map_2_length=CML2&color_map_rgb_11=RRGGBBAA&color_map_rgb_12=RRGGBBAA&color_map_rgb_21=RRGGBBAA&color_map_rgb_22=RRGGBBAA&data_values=A01 A02 ... A0N A11 A12 ... A1N ... AM1 AM2 ... AMN
The following table defines the input string key and value pairs:
| Chart Specific Entries | |
| Key | Value Description |
| chart_type¹ | The chart type is always 7 (aliased to point map), indicating a Point Map Chart. |
| chart_subtype¹ | one of {0, 1, 2, 3} (aliased to {linear , semilog, x-log y-linear, log-log}) for {X-Linear, Y-Linear}, {X-Linear, Y-Log}, {X-Log, Y-Linear} or {X-Log, Y-Log} respectively. |
| chart_format_type¹ | Always 0 (aliased to default). |
| title | The main title of the graph. If this key is not present then the template's title is used. |
| x_title | The x title of the graph. If this key is not present then the template's x-title is used. |
| y_title | The y title of the graph. If this key is not present then the template's y-title is used. |
| grid_x_length | The number of grid cells in the x-direction. |
| grid_x_minimum | The minimum x-value of the grid. |
| grid_x_maximum | The maximum x-value of the grid. |
| grid_y_length | The number of grid cells in the y-direction. |
| grid_y_minimum | The minimum y-value of the grid. |
| grid_y_maximum | The maximum y-value of the grid. |
| color_map_1_type | The color mapping type (0, 1, 2, 3). |
| color_map_1_length | Number of colors in map 1. |
| color_map_rgb_11 | Beginning color of the color mapping. |
| color_map_rgb_12 | Ending color of the color mapping. |
| color_map_2_type | The color mapping type (0, 1, 2, 3). |
| color_map_2_length | Number of colors in map 2. |
| color_map_rgb_21 | Beginning color of the color mapping. |
| color_map_rgb_22 | Ending color of the color mapping. |
| templates | A custom Templates directory. |
| data_values | A white space delimited list of values representing the z-values of the grid matrix. See Data Oriented keys for additional information and keys. |

You can also modify the following Templates:
| Template Document Names | |
| Template | Description |
| PVST_Line_Graph | Forms the static attributes for the X-Linear, Y-Linear graph. |
| PVST_X_Log_Line_Graph | Forms the static attributes for the X-Log, Y-Linear graph. |
| PVST_Y_Log_Line_Graph | Forms the static attributes for the X-Linear, Y-Log graph. |
| PVST_XY_Log_Line_Graph | Forms the static attributes for the X-Log, Y-Log graph. |
| PVST_line_color_table | Forms the line colors for odd format type indices. |
| PVST_line_color_table_1 | Forms the line colors for even format type indices. |
The following Server Side Attributes define additional non-graphic attributes. A file with this name in the templates directory will alter the parameters that appear in the attribute file.
