Dans ces cas, un graphique semi-log axes est utile. Tapez le nom de votre variable indépendante au début de la 'Une' de la colonne dans Excel. The reason for this is that the graph of Y = LN(X) passes through the point (1, 0) and has a slope of 1 there, so it is tangent to the straight line whose equation is Y = X-1 (the dashed line in the plot below): This property of the natural log function implies that. One of the main differences is that you are able to plot more points higher up the scale with the semi-log graph because the points are very close. 75" graph stickers stick practically anywhere. The Chart Wizard produces graphs with linear scales. Therefore, the revenue decreased during this period. The graph is semi-log, if one of axis is in log and the other not. Handy for functions that growl exponentially. The second reason is that the difference between semi-log scale and an arithmetic one is barely visible for the very-short-term charts, so the difference in usefulness is also barely seen.
