Show all Y axis data points in chart

Help! I created a Gantt chart to reflect deadlines over the next 5 years. With so many tasks/items listed in the y axis, Excel is reformatting the chart to only show the first 8 items. I want to show all items in the y axis - even if the chart needs to be huge. I've tried adjusting the axis interval (configured as text), min, and max values, as well as the font, but the chart only shows a portion of the total data. Any help would be appreciated. Emily
