Axis Element Attributes
The X-Axis and Y-Axis elements have the same attributes, except as noted:
| Attribute | Description |
|---|---|
| Axis Padding Left | (X-Axis only) When the X-axis presents Numeric or DateTime data, sets the padding between the edge of the plot area and the first data value, as a percentage of the axis length. This is useful for preventing the first data value from appearing at the very edge of the plot area. Set to 0 to remove all padding. The default value is 1. |
| Axis Padding Right | (X-Axis only) When the X-axis presents Numeric or DateTime data, sets the padding between the edge of the plot area and the last data value, as a percentage of the axis length. This is useful for preventing the last data value from appearing at the very edge of the plot area. Set to 0 to remove all padding. The default value is 1. |
| Axis Padding Top | (Y-Axis only) Sets the padding between the edge of the plot area and the highest data value, in pixels. This is useful for preventing the highest data value from appearing right at the edge of the plot area. The default value is 5 pixels. |
| Axis Type | Sets the scaling type for the axis. This can be a "smooth" scale, consistent with a stream of numbers or dates/times or, when working with the X-Axis element, it can also be a category (e.g. Apples, Oranges) which are often visualized using Bar and Pie charts. The default value varies based on the axis column data type: Text = Category, DateTime = DateTimeLinear, Numeric = NumericLinear or NumericLogarithmic. |
| Caption | Specifies the text of the axis caption. |
| Fixed Scale Lower Bound | Sets the lower scaling boundary of the axis. Use this attribute, for example, to cause negative Y-axis values to be plotted below the zero line (see Plotting Negative Values). Set this value to a number, or leave it blank for automatic scaling. If you specify a lower bound, then you must also specify an upper bound. |
| Fixed Scale Upper Bound | Sets the upper scaling boundary of the axis. Set this value to a number, or leave it blank for automatic scaling. If you specify an upper bound, then you must also specify a lower bound. |
| Hide Axis | Hides the axis from view. |
| Hide First Label | Hides the first tick mark label. The default value is False. |
| Hide Last Label | Hides the last tick mark label. The default value is False. |
| Line Color | Sets the axis line color. Enter a color by name, decimal RGB value, or hex RGB value. Prefix hex values with the pound sign, e.g. #112233. |
| Line Color Transparency | Specifies the transparency of the axis line color. The lowest value of 0 specifies that the background is opaque, with no transparency. At the other end of the scale, 15 specifies a completely transparent background. Use medium-level transparency to allow different chart layers to show through each other. |
| Line Thickness | Specifies the thickness of the axis line, in pixels. The default value is 1 pixel. |
| Opposite Side | Specifies that the axis be displayed on the opposite side from its normal position, or Left for vertical axes and Bottom for horizontal axes. The default value is False. |
| Reverse Axis | Reverses the axis so low and high values are swapped. Chart is then rendered to match. For example, if Y-axis is reversed, low values are at the top of the canvas and the chart is drawn "downward" from it. |
| Reversed Stack Series Order | (Y-Axis only) When there are multiple Series in use, or a DataLayer.Crosstab which generates multiple Series, and the Series are stacked, this attribute reverses how the values are stacked. |
| Spacing | Sets the space, in pixels, between the legend and chart plot area. The default value is 10 pixels. |
