What is the difference between linear graph and line graph?
Though both of them are made up of line segments, there is a major difference between them. The difference lies in the figure obtained after joining the line segments . All the points in a linear graph are collinear and hence lie on a line. But in the case of a line graph, they may or may not be collinear.
What should a line graph include?
The line graph consists of a horizontal x-axis and a vertical y-axis . Most line graphs only deal with positive number values, so these axes typically intersect near the bottom of the y-axis and the left end of the x-axis. The point at which the axes intersect is always (0, 0).

If prices are rising, draw the trendline underneath the lows. If prices are falling, draw the trendline above the price highs. If the stock is range-bound, draw a trendline above the high prices and below the low prices. At least 90 to 95 percent of the prices should be contained above or below the trendline.
