By default, the trendline will be linear. The Format Trendline dialog box opens.Now select the Trendline in the chart and right-click on it and then click on Format Trendline.This will add the trendline to the existing line graph. The Chart Elements dialog box appears.Now select the chart and then click on the “+” button in the top right corner of the Chart.Plot the line graph by selecting the dataset and then go to the Insert Tab and then click on Insert Line or Area Chart.Here, y1=2 and stored in the location B2 and y2=4 stored in location B3 and x1=1 stored in the location A2 and x2=2 stored in the location A3 of the worksheet. The array ranges from A2 to A11.Ĭonsider the points (1,2) and (2,4). The X-axis array is stored in A column of the Excel sheet. Here, Y-axis array is stored in B column. From the equation of the trendline we can easily get the slope. By plotting a trendline on the line graph and find its equation. Use the formula and “-“,”/” operators to find the slope, m.ģ.From the data set take any pair of points.Known_xs : An array of numeric data points which are independent.Ģ. These are dependent on value of horizontal axis. Known_ys : An array of numeric data points which are dependent. The syntax is : =SLOPE(known_ys,knownx_s) By using the Excel in-built function SLOPE.

The graph I'm getting from the code displays the correct red and blue functions, but the y axis is obviously not quite right, and the green function doesn't display (due to the error mentioned earlier) from scipy.misc import derivative as deriv So any assistance you can provide here would also be helpful. I'm trying to replicate a plot in Python that I've made previously in Matlab, where three functions are plotted on the same xy axes.Ī red line represents the function y=1/(1+(x^2)), a blue line represents its first derivative, and a green to represent its indefinite integral.ġ) I've tried a few different ways, but I've been unable to set the y axis range to be -1.5 to 1.5.Ģ) I'm receiving the error "ValueError: x and y must have same first dimension" when trying to plot the third line, the integral.Īs you can see in the code below, I'm actually using the definite integral from -infinity to infinity, as I also couldn't work out how to write the indefinite integral.
