Construct Chart Log For Free

Logarithmic price scales are a type of scale used on a chart, plotted such that two equivalent price changes are represented by the same vertical changes on the scale. They are generally used for the long-term perspective analysis of price changes.

When the logarithmic values of the data points or the axes are plotted on a linear axis, each data point or axis corresponds to a raw logarithmic value (e.g., 7.0 correponds to the -log (10-7); etc). Both graphs represent exactly the same data. In other words, they are there quantitatively equivalent.

Creating a Log/Log Chart Select the chart area. Make sure the Chart Design (Design in earlier versions of Excel) tab of the ribbon is visible.Click the Change Chart Type tool in the Type group.Select the XY (scatter) type of chart. Select the sub-chart type you want to use. Click on the OK button.

To create a log-log chart in Excel: Select the data that you want to plot. Click the Insert tab, and then click Scatter. Click Scatter with only Markers. Click OK. Right-click the x-axis, and then click Format Axis. Under Axis Type, click Logarithmic scale. Click OK. Right-click the y-axis, and then click Format Axis.

A logarithmic chart uses a logarithmic scale, not a linear value. A linear scale is what most charts commonly use, where values are equally spaced out like a ruler. With logarithmic scales, while the end value could be the same as the linear value, the spaces between the values are different.

A logarithmic price scale is plotted so that the prices in the scale are not positioned equidistantlyequally from one another. Instead, the measure is plotted in such a way that two equal percent changes are plotted as the same vertical distance on the scale.
