For the data points of the f(x) chart, error bars with fixed or dynamic lengths can be defined for each data series in either horizontal or vertical direction.

Introduced in PAtools 7.1 upgrade 11/2017

Error Bar Parametrization

  1. Select the data series for which you want to define the error bars.
  2. Switch to the Error Bars tab.
  3. Determine the values according to the following table.
Table 31. Error Bar Parameters
Entry Input Description
Horizontal Length Plus Constant float or control variable of type Float Length of the error bar in positive x-direction
Horizontal Length Minus Constant float or control variable of type Float Length of the error bar in negative x-direction
Vertical Length Plus Constant float or control variable of type Float Length of the error bar in positive y-direction
Vertical Length Minus Constant float or control variable of type Float Length of the error bar in negative y-direction
Error Type List selection or control variable of type Integer

Absolute value or percentage of the values for the length of the error bars; applies to both axes.

Values for control variables:

0: Absolute
1: Percent
Horizontal Bars Yes/no selection or control variable of type Integer Shows error bar in x-direction, if activated.

Values for control variables:

0: No error bars
<> 0: error bars are shown
Show vertical bars Yes/no selection or control variable of type Integer Shows error bar in y-direction, if activated.

Values for control variables:

0: No error bars

<> 0: Error bars are shown
Color Dialog selection or control variable of type Text RGB value: color of the error bar

Values for control variables: semicolon-separated (A)RGB values

Example ARGB: 255;90;174;274 (light blue)
Bar thickness Integer or control variable of type Integer Thickness of the error bars in pixels
Note

Displaying too many error bars can adversely affect graphics performance.

Error bars that are too close to each other overlap and then obscure the actual graphic points.
