A line chart can display continuous data that changes with units (for example, unit time) and is therefore well suited for displaying trends in data at equal time intervals.A scatter chart shows the relationships between values in several data series, or draws two sets of numbers as a series of XY coordinates.------------------------------------In a line chart, category data is evenly distributed along the horizontal axis, and all value data is evenly
Excel scatter charts are slightly different from other chart types, and you can select all the data and not generate scatter charts for multiple sets of data.

In general, we usually use a chart that inserts a curve directly. But sometimes, when we finish the experiment, we need to make a comparative analysis of the results. Then, you will need to draw multiple curves on a graph to compare the curves. On this, small knitting is also very confused, in order to solve this problem, small knitting specially learned the operation process. Below, the small set will be how to draw multiple curves on a

companies often display their work performance in column charts. When you make a chart in Excel, the data source of the chart is manually selected from the existing data. But sometimes the number of employees is not fixed, which means that the original data area is also variable, it is likely to continue to increase, so that the increase in data will have to manually update the data source of the chart, so that the operation is more cumbersome.
