97 These buttons allow to switch horizontal axis scale to the linear or
100 \note The logarithmic mode of the horizontal
101 axis scale is allowed only if the minimum value of abscissa component
102 of displayed points is greater than zero.
106 \image html plot2d_linear_y.png
107 \image html plot2d_log_y.png
109 These buttons allow to switch vertical axis scale to the linear or
112 \note The logarithmic mode of the vertical
113 axis scale is allowed only if the minimum value of ordinate component
114 of displayed points is greater than zero.

120 <b>Show Legend</b> - Shows / hides information about the displayed
124 \image html plot2d_settings.png
126 \b Settings - provides an access to the settings dialog box, that
127 allows to specify advanced parameters for the Plot 2d Viewer.

132 The following options are available:
134 - <b>Main title</b> is the XY plot title. By default, it contains the names of tables, from which the curve
135 lines are constructed.
137 - <b>Curve type</b> allows selecting from \em Points, \em Lines or \em Spline.
139 - <b>Marker size</b> - size of the points (markers) forming curve lines.
141 - <b>Background color</b> of the XY plot.
143 - <b>Selection color</b> - defines the color of selected object in the viewer.
145 - <b>Legend</b> specifies the legend properties.
147 - <b>Show legend</b> - specifies if the legend is shown by default.
149 - <b>Legend Position</b> allows positioning the
150 description table on XY plot (to the \em Left, to the \em Right,
151 on \em Top or on \em Bottom).
153 - <b>Symbol type</b> allows positioning the legend item symbol: "Marker on line" or "Marker above line".
155 - <b>Legend font</b> allows setting font variant, size and style for legend items.
157 - <b>Legend font color</b> allows selecting the font color for legend items.
159 - <b>Highlighted legend font color</b> allows selecting font color for selected legend items.

163 - <b>Line width</b> line width of the marker.
165 - <b>Tick size</b> size of the upper and lower horizontal lines of the marker.
167 - <b>Color</b> color of the marker.
169 - <b>Normalization</b> allows selecting the type of
170 normalization (\em minimum or/and \em maximum) for the displayed
171 presentations of 2d curves in the view.
173 - <b>Scale mode</b> allows selecting the type of scaling (\em Linear
174 or \em Logarithmic) for <b>X (Horizontal)</b> or <b>Y (Vertical)</b>
175 axes separately. Note that the \em Logarithmic scale can be used
176 only if the minimum value of corresponding component (abscissa or
177 ordinate) of all points displayed in the viewer is greater than
180 - <b>Axis ...</b> options group allows specifying additional settings
181 for each axis separately:
183 - <b>Axis title</b> - an axis title.
185 - <b>Grid / Axes marks</b> allows defining the maximum number
186 of major and minor scale divisions for a given axis. The real
187 number of intervals fits to {1,2,5}*10^N, where N is a natural
188 number, and does not exceed the maximum.
190 - <b>Save settings as default</b> If this check box is marked, all XY
191 plots will be displayed with these defined properties.

198 <b>Analytical curves</b> - provides an access to the analytical curves
199 dialog box that allows to add, remove and modify analytical curves
200 for the Plot 2d Viewer.
202 \image html analytical_curves_dlg.png
204 The options are as follows:
208 - <b>y(x)=</b> allows specifying a python expression, which is used to
209 calculate the coordinates of the curve points, where <b>x</b>
210 corresponds to the horizontal range, shown in plot 2D viewer.
212 - <b>Nb. itervals</b> allows specifying the number of the curve points.
216 - <b>Auto assign</b> if checked, the properties
217 (<em>Line type</em>, <em>Line width</em>, <em>Marker type</em> and
218 <em>Color</em>) are assigned to curves automatically. To define
219 the curve properties manually, uncheck this control.
221 - <b>Line type</b> allows to choose curve line type from \em None,
222 \em Solid, \em Dash, \em Dot, <em>Dash - Dot</em> and
223 <em>Dash - Dot - Dot</em>.
