Formatting the Lines in a Line Chart

Right-click any line in the line chart and click Format 2D Line or Format 3D Line on the shortcut menu to bring up the Format Line dialog.

In the General tab, check Ignore Null Value if you want the lines to be drawn from the previous data values to the next data values directly when null data values appear to avoid breaks on the lines.

For a 2-D line chart, set the layout style of the lines. If you want to add a 3-dimensional effect to the lines, set the Use Depth option to true and specify the depth and direction as required. Then check Smoothed Line if you want to make the lines smoothed.
For a 3-D line chart, set the thickness of the lines.

In the Fill tab, specify the fill patterns of the chart lines.

Format Line dialog - Fill 2-D

For a 2-D line chart, specify the fill type of the lines: Use Single Color or Use Single Color with Condition.
If you select Use Single Color as the fill type, in the Fill box, specify the color and the transparency of the color schema to fill the current line, that is the line you have right-clicked on to open the Format Line dialog (to change the color, click the color image and select a color from the color palette or input the hexadecimal value of a color directly in the text box). You can also click the Pattern List button to specify the color pattern for each line in the Color List dialog. In the Area box, set the fill and transparency settings of the area that are formed by the chart axes and the current line. If required, click Area Pattern List to specify the color pattern for each area formed by each line and the chart axes in the Color List dialog. In the Line box, specify the line style and line thickness of the current line. Click Line Pattern List to set the line pattern for each line in the Line Pattern List dialog.

If you select Use Single Color with Condition as the fill type, specify the conditions and the line pattern bound with each condition respectively. For details, refer to Adding Conditional Color Fills to Charts.
For a 3-D line chart, specify the color and the transparency of the color schema to fill the current line. You can also click the Color List button to specify the color pattern for each line in the Color List dialog.

In the Node tab (the tab is available to 2-D lines only), specify the fill type of the nodes: Use Single Color or Use Single Color with Condition.

Format Line dialog - Node

If you select Use Single Color as the fill type, in the Shape box set Show Node to true, then specify the style, transparency, width, height and color of the nodes in the current line, and specify whether or not to display the line nodes in the highest and lowest points with other colors and whether to show the highlight point in a distinguishing color when you hover the mouse over a node in the line. In the Border box, set the border properties of the nodes on the current line, including border color, transparency, line style and thickness. If you set the node style to plus, multiplication, star1 or star2, the Line box is available instead of the Border box, in which you can specify the line style and thickness for the nodes with selected styles. You can also click the Node Pattern List button to specify the node pattern for each line in the Node Pattern List dialog.

If you select Use Single Color with Condition as the fill type, specify the conditions and the node pattern bound with each condition respectively. For details, refer to Adding Conditional Color Fills to Charts.

If you want to make the color pattern specified on the nodes apply to the corresponding lines, check Apply Color to Line, then the color and transparency settings on the corresponding lines will be ignored.

In the Border tab (the tab is available to 3-D lines only), set the border mode of the lines, including the border style, color, transparency, line style, thickness, end caps style, and line joint mode. You can also specify whether the border is to be outlined, and whether or not to automatically resize the border dashes if the border is drawn with dashes. The specified border properties take effect only when the Border property of the chart paper is set to true in the Report Inspector.

Format Line - Border

In the Data Label tab, specify whether or not to show static data labels on the line nodes, and if to show the position of the labels related to the nodes. In the Font and Effects boxes, set the font formats and effects of the data labels.

Format Line dialog - Data Label

For a line chart in a library component, you can define web behaviors on the lines in the Behaviors tab.

Format Line dialog for library component - Behaviors

Select a trigger event from the drop-down list in the Events column, then click in the Actions column and click that appears in the text box. In the Web Action List dialog, bind a web action to the lines the same as you do to a label in the library component, which will be triggered when the specified event occurs on the lines. The web actions you can bind include Parameter, Filter, Sort, Change Property and Send Message.

To add more web behaviors, click and define them as required; if a web behavior is not required, select it and click . Click or to adjust the order of the behaviors, then at runtime when an event that has been bound with more than one action happens, the upper action will be triggered first.

Click OK to apply the settings and close the dialog.

Notes:

If the chart is a combo chart composed by lines and areas/bars, when you set the depth properties for the lines, they will be applied to the areas/bars as well, and vice versa.
For 3-D charts, the Show Static Data Label checkbox in the Data Label tab is grayed out. However, you can still see the data labels by moving the mouse pointer over the lines when viewing the report result in Designer view mode, in HTML format, or in Page Report Studio.
