### Configuration of a Data series

This is where you can configure properties of a data series.
To access this function, select [Edit] - [List of Data Series], and double-click on the target data series in the listbox.
You can also access here by double-clicking a data point on the chart.
Column No
A data series is composed of two numerical arrays. The arrays are arranged in columns in a datafile. Select two columns and relate them to axies.
For example, in "Error Bar.fig" in the "Samples" folder, the first (A) and third (C) colums in "Neutrino.prn" are loaded and plotted being related to Xb(bottomj and Ylileftj axises, respectively.
A worksheet (string grid) at the lower-left is read-only datafile browser for selecting the comumn number and loading range. You cannot edit the datafile from this software. There is a string of "12.." at the bottom of combo box for Xb, Xt axies. By selecting this, progressibe number, 1, 2, 3,..., are given as X-data instead of loading data. This feature is useful when the interval of X-data is constant.
Loading Range
You can specify the range of lines to be loaded and plotted. To specify the last line to be loaded, input the line number into the combobox, and pless [Enter].
If you want to plot all of the columns, leave there as the default setting (From [ 1] to [end]). Comment lines are automatically neglected.
Skip Loading
Number of pairs of data for a data series is restricted to 2,500. This leads not only saving of the memory size, but also reduction in file size in metafile exporting. Also, considering resolution of a generic printer, plots more than 2,500 are indistinshable and nonsense. However, thousands of data are often stored in datalogger. Skip loading is available for such a case. For example, to plot every other data, input 1. Zero means all the data are plotted.
Error Bars
Error bars can indicate certain ranges for each point such as error range, maximum and minimum, or reliable interval.
--- Setting additinal column number holding the error range---
xlow : smaller side for X-value
ylow : smaller side for Y-value
xhigh : larger side for X-value
yhigh : larger side for Y-value
-------------------------------------------------------------------------------------
In displaying standard deviation, the bar width is the same for both side.
If column number is given for only one side , the same column is specified to the other side.
Data Labels
You can put labels (data labels) that explain each data point. See "Data Labels.fig" in "Samples" folder.
Note that this feature is available only when single data series is plotted.
Basically, labels will be located at immediately below the data points (markers). If a label hides the other marker, it automatically seek other location where it does not cover the other marker. When no safe location is found, the label is not shown for the data point. In such a case, try another measure such as reducing the font size of the labels, or creating legends with arrows.
Column No: Select column number that holds the labels. Leave blank if you don't display data labels.
Font size: Font size of the data labels.
Attributes of Line

Style | You can select one in six styles.
Width | Enter line width in millimeter.
Color | If you double-click the painted rectangle, a color-select dialogbox will appear.
Spline | If you check here, the line becomes cubic sprine curve that interpolates the data points smoothly. This function is available only when the number of data series is less than 100.
Paint Below | If you check here, region between the curve and Xb-axis is painted with lighter color than that of the line. This feature is convenient to display contribution ratio as a function of time.

Attributes of Marker

Styles | You can select one in five types of the markers for data points.
Size | Enter size in millimeters.
Color | If you double-click the painted rectangle, a color-select dialogbox will appear.
3-D | If you check here, the markers are painted with gradation aiming to express Lambertian reflection.

Data Conversion
Check here and input conversion expression when you want to convert data while the datafiles are unchanged, such as unit conversion, conversion to absolute value, or conversion from resistance to conductance.
Examples:

- Conversion from Celsius to Kelvin:
  converted Y = [Y - 273.2 ]
- Conversion from hour to day:
  converted X = [X / 24 ]

Expression is case insensitive.
