Let’s look at important things here –
Mars - Mars represents our will power, courage, ability to take actions, aggressive nature, anger, our fighting ability, brother, male friends, a boy friend for a girl, a soldier, an athlete and real estate etc.
Chitra - Chitra is nakshatra of creativity, works related with pictures or images, real estate and relationship conflicts etc. For more information on Chitra Nakshatra, please read this - https://www.astrosaxena.com/citnaksh.
Virgo - As Chitra is a part of Virgo, Virgo sign and its representations also become important. Virgo is the 6th sign of zodiac belt, hence it represents almost all the things which are represented by the 6th house of horoscope like Debts, Diseases, Obstacles, Serving the under-privileged, Service Life, etc. Besides this, Virgo represents analytical or critical nature of people, being perfectionist and healing abilities. Virgo's basic representation is the lady coming in boat with wheat and herbs in her hands. So, Virgo is basically a sign of healing. Virgo consists of next set of 2 and half nakshatra. i.e. Uttara-Phalguni, Hasta and Chitra. Virgo's lord is Mercury.
Libra - As Chitra is also a part of Libra, Libra sign and its representations also become important. Libra is the 7th sign of Zodiac Belt, hence it represents the energy and things related with 7th house of horoscope, i.e. Market Place, Business, Partnerships, Relations etc. Libra is sign of Balance, i.e. striking the Balance between 2 parties/ideologies or even at personal level between our own dilemmas. It is sign of Peace and Diplomacy. And this is what we are seriously looking for after the conflicts and disagreements of Virgo, i.e. Peace to prevail. At personal level, Libra is seen as sign of Relationships. Libra is consisted of 2 and half Nakshatra named Chitra, Swati and Vishakha. Libra's lord is Venus only.
Mars - As Mars rules Chitra, Mars's position and dignity is important to know about the overall functioning of any planet in Chitra.
Mercury - As Mercury rules Virgo, Mercury's position and dignity is important to know about the overall functioning of any planet in Chitra/Virgo.
Venus - As Venus rules Libra, Venus position and dignity is important to know about the overall functioning of any planet in Chitra/Libra.
Houses Involved – Also, we can’t afford to forget the houses involved as a planet can be ruling different houses and sitting in different house for every person as per ascendant and planet’s position. To know overall affect, we have to consider the houses involved as those areas of life are being impacted.
Interpretation of Mars in Chitra Nakshatra – Chitra is ruled by Mars only. Hence, at nakshatra level, Mars is in good dignity but in Virgo section, it is in enemy sign whereas in Libra, it is in neutral dignity. So, we can consider Mars in Chitra as an average position of Mars. 1st of all, it shows that person's efforts and actions are going in creative field especially related with Drawing and Painting. They can be easily seen as Architects or working in construction related field due to involvement of Mars (Real Estate), Chitra (Picture) and Lord Vishwakarma (Universal Architect and deity of Chitra Nakshatra). Other professions which can be seen from this position are Painter, Astrologer and Lawyer. Especially in Libra section, we can see a Relationship Counselor here as Chitra is nakshatra of relationship conflicts and Libra is sign of Justice or Balance. If not, then they themselves can get into relationship conflicts and need others to counsel them. In Virgo section, they can be the most hard working people but again as Virgo is enemy sign, their efforts may not be directed in one direction. It would be scattered everywhere. In Libra section, it would be a better condition as Mars is in neutral sign. In relationship matters, they would have to be very cautious against using their aggression, dominance or aggressive speech else relations can easily spoil because this nakshatra itself represents relationship conflicts.
Role of Mars - As we are trying to interpret Mars only, we need not to look at Mars's position and dignity separately.
Role of Mercury - Likewise, Mercury placement is important to guide Moon in right direction, being Virgo's lord.
Role of Venus - Likewise, Venus placement is important to guide Mars in right direction, being Libra lord.
Other Factors – And of course, we need to consider conjunction, aspects, house lordship, house position and dashas etc to know the exact results of Mars in Chitra. So, we always need to take a holistic view of chart rather than just 1 planetary position.
Conclusion – So, this is how I see Mars in Chitra can work in a chart.
