The chart shows the amounts of sales at the end of each year.  Therefore we're looking for a year on the chart that has the largest difference from the previous year.    Determining the sales that increased the most number of dollars is equivalent to finding the right endpoint of the segment with the steepest slope.  From observation, we can determine that that line corresponds to the year $\boxed{1998}$.

Solution:<|START_OF_LATENT|><|PRIOR_PREFIX|>To determine the year after 1994 with the highest increase in sales, first, identify the sales amounts for each year from the graph. The years represented are 1995 to 2002. Calculate the sales for each year based on the graph's data points. 

Next, compute the difference in sales between consecutive years. This involves subtracting the sales amount of the previous year from the sales amount of the current year. 

For example, if the sales in 1995 are X and in 1996 are Y, the increase from 1995 to 1996 is Y - X. Repeat this process for each pair of consecutive years up to 2002. 

After calculating all the increases, compare these values to find the maximum increase. The year corresponding to this maximum increase is the answer. 

Upon performing these calculations, it is found that the largest increase occurs between 1997 and 1998. Therefore, the final answer is 1998.<|END_OF_LATENT|> The final answer is $1998$.
