Many analysis methods, such as Gann, rely heavily on the relationshipbetween price and time. When charts were drawn by hand on grid paper,it was easy to fix the price/time relationship (eg 1 grid box per week,and 1 grid box per dollar).

However, most charting applications will tend to scale the price axisand the time axis automatically and independantly, which can hinderanalysis that relies on the price/time relationship.

BullCharts has a option called "Lock scale ratio", located in the priceaxis properties. This will ensure that the horizontal spacing betweeneach bar on the chart is kept the same as the vertical spacing for thespecified number of dollars on the price axis.

For example, the chart below has been set up so that 1 day on the timeaxis is the same size as 10 cents on the price axis. In this case thegrid lines are also shown to be exactly square (though this is notalways the case).



For a detailed discussion of the advantages and use of this feature, check out the whitepaper available on the BullCharts website.
