How to Create a Line Chart

"A chart can take a large variety of forms, however there are common features that provide the chart with its ability to extract meaning from data.
Typically the data in a chart is represented graphically, since humans are generally able to infer meaning from pictures quicker than from text. Text is generally used only to annotate the data.
One of the more important uses of text in a graph is the title. A graph's title usually appears above the main graphic and provides a succinct description of what the data in the graph refers to.
Dimensions in the data are often displayed on axes. If a horizontal and a vertical axis are used, they are usually referred to as the x-axis and y-axis respectively. Each axis will have a scale, denoted by periodic graduations and usually accompanied by numerical or categorical indications. Each axis will typically also have a label displayed outside or beside it, briefly describing the dimension represented. If the scale is numerical, the label will often be suffixed with the unit of that scale in parentheses. ...
Within the graph a grid of lines may appear to aid in the visual alignment of data. The grid can be enhanced by visually emphasizing the lines at regular or significant graduations. The emphasized lines are then called major grid lines and the remainder are minor grid lines.
The data of a chart can appear in all manner of formats, and may include individual textual labels describing the datum associated with the indicated position in the chart. The data may appear as dots or shapes, connected or unconnected, and in any combination of colors and patterns. Inferences or points of interest can be overlaid directly on the graph to further aid information extraction.
When the data appearing in a chart contains multiple variables, the chart may include a legend (also known as a key). A legend contains a list of the variables appearing in the chart and an example of their appearance. This information allows the data from each variable to be identified in the chart." [Chart.

The vector stencils library "Time series charts" contains 10 templates: 3 column charts, 3 bar charts, 2 line graphs and 2 dot plots. All these charts are Live Objects displaying the data from external data source files.
Use these chart templates to design your business performance digital dashboards using the ConceptDraw PRO diagramming and vector drawing software.
The example "Design elements - Time series charts" is included in the Time Series Dashboard solution from the area "What is a Dashboard" of ConceptDraw Solution Park.
