definitely possible! have example graph line + bar in extjs demo pages itself: http://dev.sencha.com/deploy/dev/examples/chart/charts.html (refer last chart line , bar)

regarding fetching data c#.. need url send data (xml or json). so, can have java,c#,python, php or other server side technology.

extjs uses stores hold info, need have store, load data , associate store chart render data.

update have explained how handle charts series in blog. have @ above link. have similar chart (only think using line chart). json array returned server side is:

[ {month:'jan', sales: 2000, rev: 3000},{month:'feb', sales: 1800, rev: 2900}, {month:'mar', sales: 1500, rev: 3100},{month:'apr', sales: 2150, rev: 2500}, {month:'may', sales: 2210, rev: 2700},{month:'jun', sales: 2250, rev: 2900}, {month:'jul', sales: 2370, rev: 2800},{month:'aug', sales: 2500, rev: 2600}, {month:'sep', sales: 3000, rev: 3400},{month:'oct', sales: 2580, rev: 3250}, {month:'nov', sales: 2100, rev: 3000},{month:'dec', sales: 2650, rev: 3300} ]

binding store server side done through jsonreader or proxy extjs objects. need specify url need data.
