Overview
A timeline chart visualizes data trends and changes over time. It is based on a date/time field and therefore the first step in defining a timeline chart is to select a date or date/time field. The data from this field provides the timeline that stretches horizontally.
Type
Once you create a timeline chart, you can select one of the following types to best visualize your data:
- line - show data values over time as continuous lines. This is useful for showing continous values such as temperature and to show trend
- bar - show data values in points in time or time intervals. This is useful for showing monthly sales, for example. It allows you to compare the values as well as see trends and changes. When showing multiple values for each point in time, they are shown as groups of bars, and you can stack the bars to compare totals
- area - similar to line showing continuous values. The area below the line is colored. When showing multiple values for each point in time the areas are stacked to show the total and the contribution of each value to this total
- combo - when showing two values for each point in time, you can use a combo (combination) chart to show the first set of values as bars and the second as a line
- stock - show data for stock-market prices as a thin line graph that's shaded. When showing multiple values for each point it time, they are compared as lines that start at 0% and show the relative change between them. This is useful for comparing the performance of multiple stocks of time and for comparing them to a benchmark index. If a value named "volume" is the last value field, then the trading volume is displayed as a bar chart below the timeline
- OHLC - this option is available when the table has fields named "open", "high", "low" and "close". When you select this option, the data is shown as an OHLC chart
- candle - this option is available when the table has fields named "open", "high", "low" and "close". When you select this option, the data is shown as a candlestick chart
